The area you mentioned is booming because it can walk to http://maps.google.com/maps?f=d&source=s_d&saddr=S+W Dunellen Train Station http://dunellentrain.blogspot.com/ and so closed to nice Arbor Intermediate School of 4 to 5 with student Orchestra whose conductor Ms. Lee is top 5 violinist in NJ.
The wooden utility pole is not harmful, in fact, Piscataway township will remove them in the future. The major of township is very ambitious to make the whole town green with wonderful views. and as you know Piscataway just ranked #23 of Top 100 Best Places to Live in America by CNN Money Magazine http://money.cnn.com/magazines/moneymag/bplive/2008/snapshot and the area is also selected by Forbes magazine The Most Livable Metro-Area Suburbs http://www.forbes.com/2007/10/11/property-homes-suburbs-forb in Greater New York City area.
I would not be too concern about the wooden pole, but it could be your "great excuse" to negotiate the price with seller, and later after they are removed and all lines go underground, when you sell, you know you can sell more ... and you can go to Township meeting later to urge your area to be worked on first.
Piscataway township is very responsive. e.g. Birch Glen Ter area used to be hundreds of potholes, and after a few Piscataway High School students call the public works, now it is repaved and brand new. Piscataway even buy its own road paving vehicles this year, and you will see lots of change in the Spring to come this year ...
It really boils down to what matters most to you. If having a new home is most important, then your choices may be somewhat limited - and will likely include primarily "one offs" In this case, I recommend that you look for similar improvements in the area to give you confidence that you will not be alone. If you are satisfied with "new-er" then you have many communities to choose from.
Community setting vs one-off, most often buyers prefer the former.
Good luck and....

In general, this is what the consensus is:
Power lines do not increase the risk of cancer.
Power lines decrease the value of property.
However, when you buy the home, you should expect pay less than a comparable home without power lines and your subsequent sale will be similarity less. Check with your city/county to see if there is any plan to underground the lines in the future.
When selling in a sellers market, problems such as power lines, road noise, bad floor plans, neighborhood and other location problems have much less impact than they do in a buyers market.
High voltage transmission lines generally have more price effect on value than the local service lines.
